Following the adoption by Safari and Edge, all major browsers now support WebAssembly, which delivers JavaScript code compiled as highly-optimized bytecode. Bytecode, being many times smaller than the code from which it's been compiled, can be used to save bandwidth on mobile devices and help improve page loading times for modern websites and web apps.

Even from the day of the announcement, WebAssembly was insanely popular with the online gaming industry who could create more advanced gaming engines, similar to the ones used for desktop-based games. All these positive features and potential gains were why Mozilla engineers called the feature a "game changer for the web," and why work on WebAssembly went much smoother and faster than many could have predicted.
